Hi,
Finishing my basement and installing a (dedicated heating zone) baseboard around most (but not all) of the perimeter. Unfortunately, I *must* cross an entry door. What's the best thing to do?
1. go over the top of the door and install bleed valves up high?
2. break some of the concrete floor and go into floor (in a PVC or other non-corrosive material) sleeve? If this method, is there any flexible tube I can put into the sleeve? I refuse to attempt to sweat copper pipe in such an awkward situation.

Just curious on what other people have done, lessons-learned, and any other pros/cons.

Thanks
Theodore.

I'll leave the "under/over" question for others. However, I will comment on your reluctance to sweat copper if the "under" option is chosen.

Consider using SharkBite connectors.
